Why Atlas

Designed not just to generate a schedule, but to manage one.

Define your rules. Atlas pre-checks, builds, and explains — then version control and manual editing keep you in charge.

Pre-check

Catches impossible cases and high-risk conflicts before generation starts.

Smart generation

It doesn't just fill empty slots — it weighs teachers, classes, rooms and preference rules together into a schedule you can actually run.

Explainable results

See which preferences were honored, which were relaxed, and why — clearly. And if no timetable can be built, why not.

Managed versions

Save, compare, publish and roll back schedules with confidence.

Building the timetable is only half the job. Knowing why it failed is the other half.

When a timetable can't be built, Atlas finds the obstacle, proves it, and shows the change that actually works.

It doesn't guess. It tests.

Every recommended fix is re-run across the whole timetable before you see it.
